I had to remove my intake to attach an aftermarket HID kit with my xenoens because I retrofited my Angel Eyes. I have removed my intake several times before. However, This time I feel that my acceleration has dropped a little bit, Making me think that there might be a lose connection in the tube from the intake to the piping body. I will remove the intake and put it back in this weekend. Any body have similiar experiences?

I would suggest double checking every connection, filter to the piping, piping to the manifold. Also check your MAF sensor to make sure it's seated all the way in and there are no air leaks around it. Although if it were the sensor you would probably be getting a SES light I would think.
